Serial No. 883,422.

This invention relates to an apparatus for impregnating, coating orstaining bundles of shingles or similar articles, this improvement beingmore particularly applicable to an apparatus of the type shown in theapplication for U. S. Letters Patent Ser.- No. 27 4,7 83 filed May 3,1928.

One of the objects of this invention is to provide an improved form ofbasket or container which is adapted to receive and hold the bundles ofshingles while the same are dipped in the'liquid with which the bundlesare impregnated, coated or stained and also to permit more convenientlydischarging the bundles from this basket after the dipping operation aswell assimplifying the construction.

A further object of this invention is to provide means for preventingthe bundles of I shingles while being lowered with the basket into theimpregnating, coating or staining liquid, from floating out of place,and to so organize this holding mechanism that the same will be operatedautomatically upon lowering the basket into the li uid containing tankand raising the same t erefrom.

Another object of this invention is to so organize the impregnatingapparatus that i the same is lighter and more compact, also containsless parts which require manipulation for handling the bundles ofshingles, and also enables the operation of staining, coating orimpregnating the bundles of shingles to be accomplished moreexpeditiously.

I Figure6 is a fragmentary vertical section sim lar to Fig. 1 and showing theinoperative positlon of the mechanism whereby the bundles are held downin the basket.

F gure 7 is a view similar to 6 but showing the bundle holding mechanismin its operative position.

In the following description similar characters of reference indicatelike parts in the several figures of the drawings.

The numeral 10 represents the tank or chamber which is adapted tocontain a body of l quid with which the bundles of shingles or similararticles are to be stained, painted or impregnated, which liquid may besupplied to th s tank and withdrawn therefrom in any suitable manner,but preferably in the manper indicated in the above men-tionbd applica-In the lower part of this tank the same is preferably provided with anagitator consistmg of a rotary screw propeller 11 and also with meansfor heating the liquid such, for example, as a coil of pipe 12 throughwhich steam, hot water or other heating medium so may be conducted. Thebottom of this tank is closed but the upper end of the same is open soas to permit of introducing the bundles of shingles into the liquid andremoving the same therefrom. The inlet at the upper end of this tank isadapted to be covered and uncovered by a vertically movable cover 13 Iwhich is provided at its edge with a packing 14 adapted to engage with aseat 15 at theup ing a: tight joint between this cover and the tank sothat air pressure may be applied to the interior of the tank for drivingthe liquid contained in the tank into the pores of the shingles and alsopermita vacuum to be produced in this-tank for withdrawing any moisturefrom the bundles of shingles before they are dipped and also to withdrawany excess staining, painting or impregnating liquid from the shinglesafter they have been dipped.

This cover may be raised and lowered by any suitable means and alsoguided during this movement so that the same can be properly engagedwith and disengaged from the upper end of the tank. It is preferable toemploy as the guiding means for the cover a plurality of upright guiderods 16 which extend u wardly from laterally projecting arms 17 at theside of the tank and guide shoes 18 mounted on upwardly projectingbrackets or posts 19 on the cover and engaging with the respective guiderods 16.

The weight of the cover is preferably counterbalanced to facilitateraising and lower in g of the same by means of counterbalancing cords orlines 20 connected withthe upper ends of the osts 19 and connected withsuitable counter alancing weights as shown in the above mentionedapplication.

The raising and lowering of the cover 13 is preferably effected by meanswhich are associated with the means'whereby the cover is locked andunlocked relatively to the upper end of the tank. This lifting means inthe preferred construction consists of a vertically movable lifting head21 arranged centrally over the cover and guided relatively thereto bymeans of a guide piston 22 connected with the underside of the liftinghead by means of a vertical rod 23 and sliding ina vertical cylinder 24on the central part of the cover, as shown in Figs. 1, 2, and 4, and alifting rod 25 connected at its lower end with the liftin head 21 andprovided at its upper end witi a piston which is arranged within a motorcylinder 26 so that upon admitting a pressure medium alternately intoopposite ends of this cylinder the rod 25 together with the partsassociated therewith will be raised and lowered and the cover which isoperatively connected therewith will be opened and closed relative tothe tank.

The v locking means associated with this lifting mechanism preferablycomprises a plurality of sectional locking levers each of which includesan inner section 27 pivoted on the head 21, an outer section 28 guidedin a loop 29 on the margin of the cover and engaged with a locking loop30 on the marginal part of the tank, and a" spring device 31 whichyieldingly connects the inner and outer sections of each lever.

' In the raised position of the cover and V the lifting head 21 theouter ends of the outer lockin lever sections 28 are withdrawn from theloc ting loops 30 and are arranged within the guide loops 29 of thecover.

Upon lowering the cover the outer extremities of the locking leversremain in this retracted position until the cover is seated on the upperend of the tank and thereafter during the continued downward movement ofthe lifting head 29 the locking levers are straightened into horizontalposition so that the outer extremities thereof slide outwardly intoengagement with the locking loops 30, as shown in Fig. 2, therebyholding the cover in its closed position on the tank.

On the underside of the cover is mounted a 'basket which is adapted toreceive the bundles of shingles 32 or other article which is to beimpregnated, coated or stained. This basket in its preferred formconsists of a bottom 33 which is of skeleton, grate-like or open-workform, two longitudinal side walls 34 which are preferably made ofimperforate sheet metal, and a rear wall 35 which is also preferablymade of imperforate sheet metal, said bottom, side walls and rear wallbeing immovably connected so that they will be shifted as an integralunit during the oper ation of the machine. This basket is open on itsfront side so as to permit of introducing the bundles to be treated intothe basket while the latter is in an upright position, and this basketis also open at the top so as to permit the discharge of the bundlestherefrom upon tipping the basket rearwardly after the bundles thereinhave been treated by the liquid in the tank. In order to permit of thusshifting the basket relative to the cover and the tank the same ispivotallymounted upon the underside of the cover so as to be capable ofswinging about a horizontal transverse axis.

The means shown in the drawings for accomplishing this preferablyconsists of two hangers 38 depending from the under side of the coveradjacent to the outer sides of the longitudinal walls 34 of the basket,and each of these hangers being pivotally connected at its lower endwith the basket by a trunnion 37 projecting laterally from the lowerpart of the adjacent side wall 34 of the basket into a bearing oropening 38 at the lower end of the respective hanger 36, as shown inFigs. 1, 2, 4 and 5.

The axis of the trunnions 37 is arran ed in rear of the center ofgravity of the bas et which is about midway between the front and rearsides of the basket, so that the weight of the basket when in itsupright position tends to constantly turn the upper end thereofforwardly and maintain the upper end of .of the basket the front edge ofthe latter is provided with a downwardly curved or turned guide lip 40which when engaged by the lower end of the bundles will direct thelatter into the basket.

The bundles are preferably placed in the basket in a position in whichthe shingles are arranged with their length vertically and one end ofeach bundle rests on the bottom of the basket inasmuch as the bundleswhile in this position can be handled much more easily than if they restwith their sides against the bottom of the basket.

After the bundles have been thus placed within the basket the cover islowered so that the basket containing the shingles is submerged in theliquid within the tank, and after the bundles have been subjected to thetreatment for impregnating, painting or staining them as desired, thecover is again lifted so that the basket lifts the treated bundles ofshingles out of the liquid. When the cover reaches its highest positionthe attendant ushes the upper end of the basket rearwardly so that thesame turns about the axis of the trunnions 37 until the upper end of thebasket projects laterally and in an inclined position over the side ofthe tank, as shown in Fig. 5, thereby causing the bundles of shingleswithin the basket to be discharged rearwardly therefrom.

In order to prevent this turning of the basket when lowered with theshingles from being attended with a shock, the descent of the upper partof the basket is preferably cushioned or counterbalanced so that thismovement can be effected without undue jarring of the apparatus. Thepreferred means for this purpose which are shown in the drawings,consist of a spring 41 arranged along the outer side of one of thehangers 36 and connected at one end with the outer side of this hanger,while its opposite end is connected with the adjacent part of the basketbetween its upper end and. the respective trunnion 37, as shown at 42 inFigv 5.

When the basket is in its upright position this counterbalancing orcushioning spring 41 is contracted, as shown by dotted lines in Fig. 5,but when the basket is tilted or ti ped rearwardly for discharging thebundles t erefrom this spring is stretched, as shown by full lines inFig. 5, thereby absorbing the shock which otherwise will be producedwhen tilting the basket while containing the load.

It has been found in practice that when the basket and the bundles ofshingles to be stained, painted or impregnated are lowered into theliquid, that the same will float in the liquid and become displaced inthe basket and thereby not only interfere with the convenient handlingof the bundles butalso interfere with the thorough impregnating orstaining of the same.

In order to prevent the bundles from thus rising in the basket orfloating in the liquid, means are provided whereby the bundles are helddown against the bottom of the basket, which means are preferably soorganized that when the basket is in its elevated position the holdingmeans will be disengaged from the shingles and permit the freeintroduction of bundles into the basket as well as the deliverytherefrom, but'when the basket is lowered into the liquid the holdingmeans will be engaged with the top of the bundles and prevent them fromrising.

The preferred form of holding means shown in the drawings is constructedas follows The numeral 43 represents a presser which is arranged belowthe cover of the tank and is adapted to move vertically toward the topof the bundles which are arranged within the basket. This presser may beof any suitable construction but preferably in the form of a perforatedplate which is wide enough to bear against the upper side of the bundlesof shingles within the basket or other articles which are to beimpregnated, stained or coated with paint This presser is guided in itsvertical movements by means of two upright guiding and lifting rods 44:sliding vertically through suitable stuffing boxes 45 in the cover ofthe tank and connected at their lower ends with the upper side of thepresser.

The upward movement of the presser is preferably limited by stops 46arranged on the underside of the tank cover on opposite sides of theguide cylinder 2%, as shown in Fig. 4. Mounted horizontally andtransverse- 1y above the tank cover 13 is a rock shaft 47 which isjournaled in bearings 48 formed on a frame 49 rising from the upper sideof the tank cover. Adjacent to its opposite ends this rock shaft isprovided with two inward- 1y projecting rock arms 50 which are arrangedon opposite sides of the cover lifting rod 25 and each of these armsbeing connected at its free end by means of upright links 51 with theupper end of one of the presser lifting rods 44.

Between its ends the rock shaft 48 is provided. with an outwardlyprojecting rock arm 52 the outer end of which is pivotally connectedwith a vertically moving shifting rod 53. The two inner arms 50, 50 andthe outer arm 52 which are connected by the rock shaft 47 in efiectproduces a forked rock lever whereby motion is transmitted from theshifting rod 53 to the presser 43.

The upper part of the shifting rod 53 passes through a stationary stop54 which is mounted on an adjacent stationary part of the frame of themachine and above and below this stationary stop the shifting rod 53 isprovided with an upper movable stop 55 and a' lower movable stop 56.

In the uppermost position of the tank COV- er the lower movable stop 56is in engagement with the underside of the fixed stop 54, and the arms52 and 50 of the rock lever connected with the rod 53 are turned in adirection so that the outer arm is depressed and the inner arms 50 areelevated whereby the resser 43 is raised out of engagement from theupper side of the bundles of shingles, as

. shown by full lines in Figs. 1, 4 and 6.

During the initial part of the downward motion of the cover toward theupper end of the tank for the purpose of closing the latter the shiftingrod 53 is held with its lower stop 56 in engagement with the undersideof the fixed stop 54 due to the weight of the presser 43, but duringsuch movement the rock arms 52 and 50 turn about the lower end of theshifting rod 53 as a fulcrum so that the inner endof this rock leverwhich is formed by said arms and which is connected with the presser,will be turned downwardly, and the presser will also move downwardly tosome extent toward the upper side of the bundles in the basket, as shownby dotted lines in Fig. 6.

This downward movement of the presser and the rocking movement of thelever formed by the arms 52 and 50 will continue until the resser 43engages with the up r end of the undles in the basket, and t ereafterthe presser and the shifting rod 53 move downwardly in. unison with thebasket so that the shifting rodv 53 slides downwardly through the.stationary stop 54. When the basket reaches the lower end of itsmovement the upper stop 55 of the shifting rod 53 engages-with the upperside of the stationary stop 54, as shown y full lines in Fig. 7 therebyholding the presser 43 positively in its lowered position in engagementwith the bundles in the basket and preventing the buoyancy of thebundles from floating them in the liquid.

As the basket is raised subsequent to the submergence of the bundles inthe liquid the presser plate remains at rest against the upper side ofthe bundles and the shifting rod 53 will slide upwardly through thestationary stop 54 until the lower movable stop 56 engages with theunderside ofthe stationary stop 54, after which the u ward movement ofthe shifting rod 53 wil be arrested and thereby cause the rock leverformed by the arms 52 and 50 to be turned as the cover continues itsupward movement, and thereby raise the presser 43 from the top .of thebundles and release the latter during the last part of the upwardmovement of the tank cover, as shown by full lines in Fig. 6.

The u per and lower stops 55 and 56 on the shiftin rod 53 can be raisedor lowered on this ro so that the engagement of the movable stops withthe stationary stop can be re lated to suit the height of the bundles orod ihr articles which are carried in the basket for submergence in theliquid and also to vary the amount of lift of the presser from thearticle under treatment to suit differentconditions.

The operation of lowering the presser upon the bundles of shingles orthe like and lifting the same therefrom is eifected automatically duringthe lowering or raising of this function on the machine.

After the basket has been elevated and the presser has been disengagedfrom the top of the bundles in the manner described, the operator pushesthe upper end of the basket rearwardly so that it turns into arearwardly inclined osition and discharges the bundles contained thereinover the rear side of the tank to an apparatus which subsequentlyoperates upon the bundles, such for example as a machine which operatesto remove the excess liquid stain from the shingles preparatory tostacking or storing the same ready for shipment to the trade.

As a whole this machine is very compact in construction and also verysimple and light, audit also requires a minimum amount of manual effortto control its operation, thereby enabling the output of the machine tobe materiall increased and the cost of the work to be re ucedaccordingly.
